Need to escape curly braces when passing {status}

[Poorchop]

If a stream title has curly brackets in it, they need to be escaped at least when passing the title to mpv. I wasn't sure how you would want to handle this - I was thinking of just parsing the title for {} and escaping them, but since this might just be a problem with mpv, then it maybe there should first be a check for the default player, which could get more complicated. Or maybe it should just be parsed and escaped as necessary only when {status} is passed as a custom player arg.

To escape the curly brackets, just double them. Example: {random title} -> {{random title}}

Why would the curly brackets need to be escaped?
This should actually work fine:
mpv --title "{foo} {bar}" /path/to/file

These are the chars which are being escaped right now.

This is actually a livestreamer issue, not an mpv issue. In your livestreamerrc, try player-args=--title="{Livestreamer}" {filename} and you will get a KeyError. If you change it to {{Livestreamer}} instead, then the stream will launch with the expected title of "{Livestreamer}".

Ok, I see, thank you...
